Just to remark, there is much more than Wifi and Bluetooth in the 2.4 GHz and 5 GHz going.
There other users like ZigBee and many industrial users as well. Especially the industrial users have problems. Because there is no licensed band for them, they have to work in the unlicensed as well. Industrial users have stronger real time and reliability requirements than Wifi can offer (response times in ns).
Technologies like LTE will hurt innovation for industrial usage.
- mentat 11y agoCan you expand on "have to use unlicensed"? Is that really saying "don't want to deal with global regulatory systems"?
- PinguTS 11y agoNope. At least in Europe, there are working on to get their own frequency. There are also first contacts made to regulating bodies. But we learned, it is very complicated with lots of intransparent groups and clubs of those regulating bodies on national, Europe and international level. That means it will take at least 10 years and than additional years to then transform those international agreements into national regulations. So, to be honest nobody believes that it will work out. The industrial industry is very diverse compared to telcos. There are only 3 different telcos in Germany. There 3 or 4 telcos for the whole US. So they have a different market position.
- tzs 11y agoWouldn't devices for industry be certified under part 18 as ISM devices rather than as part 15 devices? Part 18 allows much higher power than part 15, which should allow the ISM users to deal with interference.
